Abstract excerpt
We have used functional complementation of Escherichia coli pur mutants to clone avian cDNA encoding 5-aminoimidazole ribonucleotide (AIR) carboxylase-5-aminoimidazole-4-N-succinocarboxamide ribonucleotide (SAICAR) synthetase, the bifunctional enzyme catalyzing steps 6 and 7 in the pathway for de novo purine nucleotide synthesis. Mutational analyses have been used to establish the structure-function relationship:...
